On porous material such as concrete, plaster, brick, wood, the moisture content of the substrate should be measured, as the presence of moisture within a material will result in poor adhesion, premature coating failure and poor appearance.
It is not sufficient to simply ensure that the surface is dry as often the surface of the substrate is the dries point - due to evaporation. It is important to establish the moisture content within the substrate itself.
The Elcometer 7410 Concrete Moisture Meter is an accurate and easy to use non-invasive instrument for non-destructive measurement of moisture content of concrete.
The electrodes transmit parallel low frequency signals, calibrated to give average moisture content by comparing the change in impedance between damp and acceptably dry concrete.
Calibrated ready for use on concrete
Instant readings on a clear, easy to read scale
Fully portable, battery operated and non-destructive
